[Boost-build] AIX hardcodes paths shared libs with generated link command

Hi,

I am having some problems linking on AIX with bjam
using toolset=gcc. In my project I have one executable
and one shared lib. Bjam generates the following
linker command for the executable:

"g++" -o <all-object-files>
"../util/bin/gcc-4.2.4/debug/threading-multi/libspeedo_util.so"
 -lrt  -g -Wl,-brtl -pthread
-Wl,-blibpath:/usr/lib/:/speedo/lib:/usr/local/lib

Now this results in an executable that does NOT look
for libspeedo_util.so in any other directories than
the relative path
../util/bin/gcc-4.2.4/debug/threading-multi! 

This is clearly not what I want. I found that if I
link the executable manually like this (with
-lspeedo_util and the corresponding -L) it works like
expected:

"g++" -L"../util/bin/gcc-4.2.4/debug/threading-multi"
-o <all-object-files> -lspeedo_util -lrt  -g -Wl,-brtl
-pthread
-Wl,-blibpath:/usr/lib/:/speedo/lib:/usr/local/lib

So my guess is that the native AIX linker works
different in this respect from the gcc linker on
Linux. Is there an easy way to rewrite the linker
command in gcc.jam with -L<path-to-lib> and -l<lib>?

Cheers,
Andrej
